Troughed belt conveyors with horizontal curves were brought to industrial use by BEUMER. Because of their curved routing and minimum curve radii, these systems offer a low-cost alternative to systems, made of straight-line units with transfer points. By transporting material simultaneously in both directions utilizing the top and bottom belt strand, it permits the customer to operate the system in an even more economical way.
With this technology BEUMER has set new milestones.

Transport devices are intended for continuous transport of overburden, coal or extracted rock in open-pit mine conditions.
The basic transport devices manufactured by UNEX Inc. are conveyors with rubber belts stiffened with textile or steel-cord meshwork. Belt width ranges from 1 200 to 2 250 mm and their max. transport capacity is up to 10 000 m3/h. Depending on the mining technology conveyors can be design in two versions: movable or immovable.
Driving and return stations can move on rails (in axis or fanlike fashion) using rails or caterpillar undercarriages (rigid or load sensitive).
For extreme conditions (contact pressure of lower than 0,07 Mpa) the driving and return station can be design by means of hydraulic walking undercarriages.
Adjusting and adapting every individual conveyor in accordance with customer requirements and technological conditions is a matter of course.
All parameters of transport devices are in-tune with a series of UNEX bucket wheel excavators. Together with additional equipment for loading, directing and deflecting material flow they form complete technological complexes. The conveyors are able to work in fully or semi-automatic mode. Maintenance costs are minimal.

Belt conveyors of the LEGMET are dedicated for underground mining of ores and should be installed in haulage routes incorporating high-capacity conveyors. The LEGMET conveyors can be also used in other industrial sectors whenever haulage equipment with adequate parameters is desired.
Design of the LEGMET conveyors makes it possible to use the equipment for heavy-duty and very specific applications. The conveyors are widely operated in copper ore mines of the KGHM Polska Miedź S.A. (KGHM Polish Copper plc.)
The LEGMET conveyors use belts of 1000 - 1200 mm width. They can be applied to material haulage with rates up to 1000 - 2000 t/h in underground workings with incline angle up to +15° and decline angle to -5°.

Belt Conveyor Systems continuously transport bulk materials, excavated and crushed rock material in a clean and efficient manner over long distances, through curves and up and down via considerable inclinations. The design parameters strongly determined the climatic conditions and material properties.
Tenova TAKRAF Belt Conveyors can be stationary, shift able, enclosed, running in tunnels over long distances, mounted on sleepers, on rails and onto the tunnel roof. The belt width ranges from 1 m to 3 m, the maximum belt speed today reaches 6,1 m/s in copper mines (even 10 m/s on conveyor bridges).
Besides countless belt conveyors in lignite mines worldwide, in 2000 Tenova TAKRAF built a conveyor system with the world longest 16.8 km single conveyor , thereof 16 km inside of an inclined tunnel. Milestones in the development of conveyor systems are installed downhill overland conveyor of El Abra and the in pit and ex pit conveyors of the Escondida mine in Chile.

Milltronics weighfeeders from Siemens can improve the accuracy of processing, blend consistencies, accountability, and record keeping. All weighfeeders come standard with a belt weigh bridge and speed sensor. An integrator is required to complete the system.
The weighfeeder is used to deliver an accurate mass flow rate of material. In the majority of applications, material is profiled by an adjustable mechanical shear gate, which fixes the correct material bed depth for a given particle size.
The feed rate is then maintained and adjusted by varying the speed of the belt. However, in some cases the belt speed is constant with rate control (if any) done by a pre-feeding device.
The system consists of three components: weight and speed sensing, integration and control, and the mechanical conveying system.
Using the belt load and the belt speed signals, small incremental totals of weight per time are measured by the integrator and then the flow rate is calculated. The measured flowrate is compared against the desired flowrate and the on-board PID controller makes necessary corrections to the belt speed.

These machines are suitable to dose in continuous powder, granular and fibre materials. They are particularly suitable for fluid materials and can reach feed rates up to several tons per hour.
As belt feeders can be installed directly under a silo or pre-storage hoppers, while as weighing belts can be re-filled in continuous from other extractor machines such as screws, stellar valves other belts. These machines are equipped with a weighing bridge with loading cells and they can be also equipped with different control devices suitable to satisfy the most various dosing and weighing needs, both in continuous and batch.

The line of IMER Group belt conveyors stands out for the versatility of its applications in the work yard. Our range is made up of LT 1200, LT1500 telescopic and LT1600 telescopic.
The belt conveyors are driven by a hydraulic transmission in vertical position capable of turning 280° around their axis, facilitating their positioning and manoeuvrability, even on uneven ground. During the distribution, the truck must remain parked in the area where it is positioned.
The speed of the conveyor is independent of the vehicle that carries the mixer or of the auxiliary motor, as it is provided by a hydraulic fixed displacement motor connected to the conveyor drive roller, which in turn is driven by a hydraulic pump connected to the power takeoff of the vehicle transmission.
The conveyor structure is made of steel with a high yield point providing the necessary sturdiness and elasticity. The accurate design and the constant attention to the requirements of the end user gives the belt conveyors reliability, and allows easy access to all their parts for cleaning and maintenance.
The conveyor makes it possible to easily and immediately distribute, at the desired point, the material contained in the mixer: concrete, gravel, sand, cement-bound granular material, etc.
The conveyor is ideal in the building of foundations, small floors, and also concrete pillars and road works. It is an ideal means, both in functional terms (flexibility and versatility, even in severe conditions) and in economic terms.

The LTB conveyor belt is the most cost-effective solution for transporting materials such as concrete, sand, crushed stones or pebbles from the truck mixer into the building site.
